BBC America announced Wednesday that it has picked up a second season of its sci-fi/fantasy series "Atlantis."

The 13-part series premiered on Saturday and attracted 838,000 viewers. This made it the highest-rated series premiere ever for the channel's Supernatural Saturday. "Atlantis" is also the most successful new Saturday night drama to air on all BBC channels since 2006.

The series imagines the lost city of Atlantis as an adventure world and battleground for some of the most legendary names in Greek mythology. It weaves a fantastical tale featuring Jason (Jack Donnelly, "Dancing on the Edge"), Hercules (Mark Addy, "Game of Thrones") and Pythagoras (Robert Emms, "War Horse").

"Atlantis" is produced for BBC by Urban Myth Films, and co-produced by Cymru Wales. Johnny Capps, Julian Murphy and Howard Overman serve as executive producers for Urban Myth Films.

"'Atlantis' is off to a fantastic start and is the centerpiece of our Saturday nights for the next twelve weeks," said Richard De Croce, senior vice president of programming for BBC America, in a news release. "We’re committed to bringing our viewers even more entertaining episodes inspired by Greek mythology from Howard and the talented team in season two.”
